First of all, the Gentle Leader® Headcollar is NOT
a muzzle. When fitted properly, your dog is free to open his mouth to
eat, drink, pant, fetch, bark and even bite - except when you close
his mouth by pulling on the leash.
The Gentle Leader® Headcollar features two soft nylon
straps - the collar portion fits high at the top of the neck, and the
nose loop fits loosely and comfortably across the base of the muzzle.
Each strap has a distinct and important effect.
The Nose Loop - Dogs are naturally "pack"
animals with a highly structured social order. One of the ways the "pack
leader" will demonstrate his position is to gently but firmly grasp
a subordinate's muzzle in his mouth. This is a non-aggressive, very
clear signal regarding who's the boss! The Gentle Leader®'s
nose loop encircles your dog's muzzle in this same manner, letting
him know in his own language that you are his leader. Dogs feel
more secure when they know who the leader is.
The Neck Strap - Have you noticed how puppies
seem to melt in relaxation when their mother picks them up at the back
of the neck? Gentle Leader® applies pressure to the back
of the neck rather than the front of the throat, working with your
dog's natural relaxation instinct with an amazing calming effect. Also,
dogs tend to pull against pressure so the gentle pressure at
the back of the neck causes the dog to pull backward, not forward.
This means an end to leash-pulling forever!
Teaches "Sit" - The Gentle Leader® Headcollar
quickly encourages controlled sitting - raise your dog's nose skyward
and he lowers his hindquarters - no pushing or shoving.
Stops Pulling & Lunging No more tug-of wars, jerking, or being
dragged down the street - even children and the elderly can walk large
or difficult dogs.
Won't Choke Gentle Leader ® gives you control with
humane restraint - pressure is applied at the back of the neck instead
of the front of the throat.
Prevents Jumping Easily stop jumping and other unwanted behavior
as the Gentle Leader® Headcollar helps you control your
dog in a "stand", "sit" or "down" position.
Not a Muzzle When fitted properly, your dog may open his mouth
to eat, drink, pant, fetch and bark - except when you pull on the leash
to close his mouth.
Controls Barking Stop unwanted barking with a simple pull of the
lead to close your dog's mouth - no need to shout or scold.
Aggression Problems Under the supervision of a professional trainer,
veterinarian or behavior consultant, and when used appropriately, Gentle
Leader® can be very effective for aggression problems.
Stops Begging Eliminate annoying behavior at meal time and helps
the kids hang onto their snacks!
